COMPUTINGANDINFORMATICS .
Time: Three hours
Maximum marks: 100
Answer FIVEquestions, taking ANYTWO'from Group A,
ANYTWOfrom Group B and ALLfrom ~roup C.
All parts of a question (a, b, etc) should be
answered at one place.
Answer should be brief and to-the-point and be supplementedwith neat sketches. Unnecessary long answers may result in loss of marks.
Any missing data or wrong data may be assumed suitably giving proper justification. Figures on the right-hand side margin indicate fun marks.
Answer to aUparts of the same questions must be grouped toge1her in one place. This is applicable to subparts as well
Group A

Basic Hardware, Operating System, Translator,
Editor and Application Layer. 5
(b) Distinguish between an Information system and a File system. 5
( c) Write a C program that will accept an integer N as input if and only if that integer N lies within 0-9999.Then it will produce the summation of its digits and lastly prints the integer as well as the summation. 3 + 7
2. (a) What. are the key features of a LAN? 8
(b) Convert 123789 decimal into its equivalent Binary Number. Clearly depict all steps. 7
( c) Write a C++ program to generate a series of pseudo random numbers. 5
3. (a) Specify the key differences between an impactpnhrer and a non-impact printer OR a graphics printer and
a character printer with relevant examples. S
(b) Specify the various processing steps that are needed in exact sequence when any existinghigh level source
program like a C program file stored on Disc is to be executed on a PC. Clearly mention the various system Software modules involved clearly highlighting their roles. 8
(c) Write a C function that willcompute the K in largest and K in smallest element alongwith their positions
in an array ofN signed integers. Assume the following 5::::N ::::50 and 1 ::::K 4. (a) What are the distinctive features of a Relational Data Base? Specify with some examples. 4

6. (a) Write C function for implementing the following operation on a singly linked linear list of integers:
(i) Create List (List)-Creates the list and returns its head pointer. 4
(jj) Find {Listelement)-5earches for the specified element within the specified list, Returns the leftmost node number within the list that has a value equal to the element (if found) or return (O)if not found. 8
(b) What are the various types of resource management modules (if any) that are pre.sent in any operating
system? Specify their functionality in brief. 8
7. (a) Specify an algorithm that can be used to convert a +ve binary integer into its equivalent Hex value.
Clearly depict all steps. What will be the associated data structures? 14
(b) Construct a R-S Flip-Flop usmgNOR gates only. 6
8. (a) What are the key characteristics of a Network protocol? Why protocols are needed? 6 + 4
(b) What is Spooling? 5
